- Mammalian Lung
- Lungs are inside the THORAX
- surrounded by PLEURAL MEMBRANES
- these secrete Pleural fluid
- Pleural fluid provides an AIRTIGHT, SLIPPERY covering
- allows lungs to inflate and deflate easily
- Pleural fluid provides an AIRTIGHT, SLIPPERY covering
- these secrete Pleural fluid
- Air passes down into lungs via the TRACHEA
- This then branches to the LEFT+RIGHT BRONCHI
- Each bronchus branches repeatedly to BRONCHIOLES
- These lead to bunches of tiny sacs called the ALVEOLI
- Each alveolus has a blood capillary very closely associated
- this allows the exchange of oxygen and C02

- The movement of lungs provided by the DIAPHRAGM
- A sheet of tissue containing muscle
- Separates thorax from abdomen
- And the muscles between the ribs- the INTERCOSTAL MUSCLES
- Separates thorax from abdomen
- A sheet of tissue containing muscle
- Rib Cage protects the lungs from damage
- And protects the heart
